What do you mean by streamlined? That suggested something other than appearance.
The article mentions a dated appearance for one of the packages, but if the dated appearance is ultimately more usable and faster to manage, that matters more to me than what the desktop looks like when it is sitting idle.
To me, “streamlined” means no unnecessary bells and whistles (at least by default). No fancy fading in and out, eye-candy sort of stuff. It still does everything I ask of it, though.
